To all whom t may concern:

Be it known that we, DORsAY MGCALL WHITE, a loyal subject of the King of England, and LYLE K. SNELL, a citizen of the United States, both residents of Detroit, Wayne county, State of Michigan, have invented certain new and usefu'l Improvements in Hydrocarbon-Motors, of which the following is a specification.

This invention relates to hydrocarbon 1110-' ors, and particularly cooling systems there- With the increased number of cylinders used in a modern high speed internal combustion engine, particularly the water cooled type, considerable difficulty has been encountered in efforts to provide simple and eiicientmeans for maintaining the cooling medium at a proper uniform temperature in the various cylinder blocks.

In previous cooling systems, where a single path circulation is used for cooling a multicylinder motor, it is frequently found that when the temperature is maintained suiliciently high in` the` cylinders adjacent the inlet to the water jackets, the temperature in the jackets of the cylinders remote from the inlet becomes dangerously high, and in order to maintain the temperature of the cooling medium in the jackets of the cylinders remote from the water inlet below the desired maximum, the temperature of the cylinders adjacent the inlet must be kept too low for efficient operation; therefore, one of the salient objects of this invention is to improve the arrangement and disposition of the parts, and to materially increase the eiciency of cooling systems, particularly adapted for use with hydro-carbon motors, of the multi-cylinder type.

j Another object is an arrangement of circulating paths which will minimize the difference in temperature of the cooling medium in the various cylinder blocks of a multi-cylinder motor.

Another object is to provide a cooling system which will maintain all of the cylinders at a substantially uniform temperature.

Another object is to decrease the length of the paths of circulation of the cooling medium and at the same time improve the general efficiency of the system.

Another object is to provide each of several water cooled cylinder blocks with an independent circulating cooling system, which may use a common radiator.

Another object is to provide an internal combustion engine comprising a plurality of cylinder blocks, with improved means for independently circulating the cooling medium, as by parallel paths, through the jackets of the various cylinder blocks,

Other objects will appear from the following description taken in connection with the drawings which form a part of this specification, and in which:

Figure 1 is a side elevation of a power plant of a hydrocarbon motor, comprising an embodiment of this invention;

Fig. 2 is a front elevation of the power plant illustrated in Fig. 1, with the radiator removed and showing certain portions broken away;

Fig. 3 is a horizontal section, substantially on the lineS-S of a regulator shown in-Fig. 2.

Fig. 4 is a vertical section substantially 'on the line of the same regulator and pump mechanism, shown in Fig. 2; and

Fig. 5 is a rear elevation of the upper part of the radiator shown in Fig. 1.

Referring to the drawings, 10 represents a crank case; 11. and 12 a plurality of cylinder blocks mounted thereon, in any suitable manner, in V relation. Each of the cylinders are provided with the usual valve mechanism 13 operated by means or rocker arms 14 and a cam shaft 15, which may be driven by gearing not shown, from the crank shaft 17. The crank shaft is adapted to be driven by means of pistons 18, which are connected to the crank shaftl? by connecting rods 19, and piston pin 20 and crank pin 21.

A shaft 22. arranged transversely to the crank shaft 17 and adapted to be driven therefrom, through the gears Q3 and '24, is shown as mounted in suitable bearings Q5, arranged in the crank case 10. rlhis shaft is adapted to drive a plurality of pump mechanisms arranged at each end thereof, and which will be more particularly described hereinafter.

Each of the cylinder blocks 11 and 12 is also provided with an independent cooling means, comprising water jackets 26, having an intake port 27 arranged adjacent one end of the cylinder block. An outlet portl 28 may be provided adjacent the end of the cylinder block remote from the intake port 27. This outlet port 28 may the-n be connected, as shown, by means of a conduit 29 and a common return 30, which is at? tached at 3l in any well known manner, td

a common cooling means or radiator 32 for both of the cylinder blocks. Arranged adjacent to each side of the lower portion of a radiator 32 are ports 33, each of which, has suitable connections, as by conduit 34' and conduit 35 with the intake port 27 for the jackets of the respective cylinder blocks.

While a pump mechanism and thermostat control, indicated at 36, and which will be more particularly described hereinafter, is shown as arranged between the conduits 34 and 35, it is not essential that such mechanism and thermostat be included in this system as it will be seen, this invention is as applicable to thermo Siphon systems.

We have also provided a connection or bypass 37, communicating with the conduit 29 and adapted to be connected with the conduit 35, so that the circulating medium may iow through each of the cylinder blocks 11` and l2 independently of each other, and independent of the common return 30 and common cooling means 32, as will more articularly appear from the description o the operation of preferredforms of the system, as hereinafter set forth.

Pump mechanisms 36 and thermostat control, above referred to brieiy, which may be provided for a force feed circulating system, comprise a two part casing 37 and 37", suitably connected, as by bolts 38, to opposite sides of the crank case 10. Suitabl arranged in bearings lin said casing 37 are two pump shafts 39, each having a pump impeller 40, suitably secured thereto, as by a pin 41, this shaft 39 being preferably detachably connected, as at 42, to an end of the transversely arranged driving shaft 22 hereinbefore described. Suitably secured to the top of the casing 37, as by bolts 43, is a cover or valve chamber, provided withvan inlet port 45, adapted to be connected with the conduit 34. The port 45 communicates with an inner shell 46, shown as formed in'- tegral with the chamber 44 and provided with ports 47 and 47, adapted to be controlled by a valve mechanism, which will be more particularly described hereinafter.

lt will be seen that the chamber 44 is provided with a plate 48, suitably secured thereto, as by bolts 49 and provided with a port 50 `and nipple 5l communicating therewith, the nipple having the bypass 37 suitably thereto. Arranged in the boss 52 formed in the casing 37` is an adjustable member 53. to which is secured as by a threaded connection, an automatic control in, the form of a thermostat member 54, to which is secured upper and lower valve members 55 and 56 respectively, which form, a balanced valve for controlling the flow of cooling medium from 'the port 45 to the inside 57 of the pump casing, the upper valve, it will be seen, being adapted to restrict the how of cooling medium through the port 50 when the ports at 47 and 47 are opened.

Arranged between the cylinder blocks 11 and l2 is a gas inlet 58, which is secured as by bolts 59 to said blocks. A carbureter 60 is shown as connected to said gas inlet. The inlet 58 is also shown as provided with a water jacket 6l, having a plural-ity of inlet ports 62, each of which 1s shown as connected as by conduits 63 to the upper part 64 of the cylinder jacket of one of the cylinder blocks. The water jacket 6l. is also provided with a plurality of outlet ports 65, each of which is shown as connected by conduits 66 to a port 67, formed in the cover 48.

It will also be understood that the valve member 55 may be provided with a notch 68 formed therein, adapted to 'permit a circulation of water through the jacket 51, even though the vport 50 is restricted by the valve member 5l.

It will be seen from the above description that we have provided a cooling system adapt/ed for use in a hydrocarbon motor, comprisinga plurality of cylinder blocks, each of which has independent circulating paths, as well as independent means for supplying cooling medium to its circulating' system.

The operation of the cooling system for each of the blocks is as follows:

Assuming the motor to be started when the cooling medium 'is below the desired temperature, the thermostat 54 will close off at 47 and 47 the communication of the port 45 with the inside 57 of the chamber 37', 37 and the cooling medium will be drawn in the pump at 69, discharging it therefrom through the conduit 35 to the cylinder jacket at 27 and thence into the conduit 29, and, as the radiator 32 is cutoff from the pump chamber, the cooling medium will be bypassed through the conduit 37 to the chainber 57 and then returned, as described. Thus it will be seen, that with the thermostat in this position the cooling medium circulates through each of the blocks independent of the other. l

However, when the temperature of the cooling` medium rises above a predetermined height. the thermostat 54 raises the valve members 55 and 56 and restricts the How of water through the port 50 to the chamber and the cooling medium will circulate from the pump, through the same circuit as when the communication with the port 45 is cut off. until the water Hows to the conduit 29, where it will continue to flow to the com- Leanne mon return 30 and radiator 32. With the l valve in this position, it will be seen that a parallel circulating system is provided through each of the cylinder blocks, with a means in the form of a common radiator or common return, for equalizing the temperature in the various blocks.

It will also be understood that there is a continual thermo siphon circulation throughl the jacket 61 of the intake 58 regardless of the position of the thermo controlled valve, as the iibtch or port 68 formed in the valve member 55 permits a restricted iiow of water therethrough.

By providing parallel independent circulation paths for the various cylinder blocks, as destribed and illustrated, it will be seen that 4we have clearly minimized, by shortening the'paths of circulation, .the difference in temperature of the cooling medium in the various cylinder blocks, and have rendered the temperature substantially uniform, while at the same time providing a very simple and compact arrangement of parts.

It will be understood that'while we have shown two separate pump mechanisms, each provided with its own thermostat, it is obvious to one skilled in the art that the two pump mechanisms may be grouped into one and controlled by a single thermostat.

While We have shown and described a preferredv form of our invention, it-will, of

course, be obvious' to one skilled in the art,

'that various modifications may be made without departing from the .spirit or scope of our iinvention, which will be covered by the clalm's.
